SWEEP-OPERATED WINDLASS.

Application filed. May 14;, 1908.

b all whom it may concern:

Be it known that I, Ariroxzo C. VAN Strum, citizen of the United States, residing at Cresco, in the county of Howard and State of Iowa, have invented new and useful l m n'oveinents in Sweep-Operated indlass, of which the following is a specification.

My invention pertains to sweep-operated windlasscs such as are designed more particularly for use in pulling stumps; and it has for its object to provide a strong, efficient and easily controlled sweep-operated Windlass, of simple and inexpensive construction, and one in which adequate provision made for eeping a cable in order and preventing frictional wear thereof.

The novelty, utility and practical advantages of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a side' elevation of the windlass constituting the best practical embodiment of my invention of which I am aware. F 2 is a plan view of the windlass. Fig. 3 is a detail view, partly in elevation and partly in vertical section, illustrating my novel means for put-ting the drum of the Windlass in and out of gear Fig. 4 is a horizontal section taken in the plane inclicated by the line 4-t of Fig. 1, looking downward, and with a portion of the frame of the windlass broken away. i Fig. 5 is a broken elevation, partly in section, showing the spindle of the Windlass and certain appurtenances thereof. Fig. 6 is a plan view of the vertically adjustable clutch member comprised in my improvements, and: Fig. 7 is an inverted plan view of the spindle.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which A is the bottom plate of the Windlass, which is bolted or otherwise secured on transverse timbers a fixed with respect to longitudinally disposed timbers b, and is provided with a central raised portion 0, and a stud (Z, see dotted lines in Fig. 1, rising from the center of the said raised portion 0. The timbers a and 6 form a rectangular base frame, and I prefer to strengthen the said base frame by using metallic bars 0 which extend between and are connected to Specification of Letters Iatent.

Serial No. 432,957.

the transverse timbers a and are arranged above the longitudinally disposed timbers b, as best shown in Fig. 2.

B is a top casting which is arranged a suitable distance above the bottom plate A and is providel with a central, circular bearing 6 for the upper portion of the drum, presently described.

C is a front upright, preferably of metal, having angular end portions arranged parallel with and connected to the base plate A and the top casting B.

D is an upright roller interposed between and journaled in lateral lugs f on the said portions j and having for its office to prevent frictional wear of a cable incidental to the passage of the same to and from the drum, and E is an open frame bolted or otherwise fixed to the opposite ends of the bottom plate A and top casting B, with reference to the upright C. The said open frame E, which is preferably of metal, is provided in its outer portion with an open ing g, the outer wall of which is notched at intervals of its height, as indicated by h, for the connection of an anchor cable (not shown); the plurality of notches in being provided in order that the anchor cable may be connected at various heights to the frame E in order to meet different conditions.

F is the drum of the apparatus which is mounted on the raised portion 0 of the bottom plate A, and has a reduced upper portion 2', see Figs. 1 and 3, journaled in the circular bearing 6 of the top casting B, whereby it will be manifest that the drum is adapted to be freely rotated about its axis. Extending vertically through the drum F is a spindle G, the lower end of which is disposed over the stud d on the bottom plate A so as to enable the spindle to hold the lower end of the drum against casual movement or displacement. The drum is loose on the spindle and hence is enabled to freely turn in either direction about the same.

As best shown in Figs. 1 to 3, the drum F is provided adjacent to its upper end with a circumferential series of ratchet teeth j,

and is also provided with a circular series of clutch teeth is, and a hand ring Z; the clutch teeth 76 being arranged on the upper end of the reduced portion 2', and the hand ring Z being arranged below the ratchet teeth j and being designed to enable an attendant to turn the drum in either direction by hand. I also prefer to provide the drum with the usual holes at for the connection of a cable.

The drum F is designed to be sweep-operated in the direction indicated by arrow in Fig. 2, and with a view of preventing retrograde movement of the drum 1 provide the dog a, pivoted on a stud 2) depending from the top casting B, and arranged to engage the ratchet teeth j on the drum. The said dog a is normally maintained in the position illustrated by a coiled spring 1 connected to the front upright C, and in order that the dog may be disengaged from and held out of engagement with the teeth 3', as when it is desired to turn the drum in the direction opposite to that indicated by arrow, 1 provide the cam lever s which is fulcrumed on a stud 6 depending x from the top casting B and is arranged in engagement with the outer arm of the dog, after the manner best shown by dotted lines in Fig. 2.

H and I are lower and upper brackets fixed to the inner upright bar of the open frame E and curved in conformity to the drum, Fig. 4, and having apertured lugs a.

J and K are lower and upper brackets fixed to the front upright C and arranged at the opposite side of the drum, with reference to the brackets H and I, and curved in conformity to the drum and having apertured lugs 41.

L is an upright roller arranged at one side of the drum and M is an upright roller arranged at the opposite side of the drum. These rollers L and M have for their office to bear against the superposed coils of a cable on the drum and retain the same in proper order, and they may be spirally grooved as shown, or else may be provided with plain peripheries in the discretion of the manufacturer of the Windlass. The roller L is carried by a horizontally swinging frame N, pivoted at w to the brackets H and I, and provided with lugs 00 in which and the lugs u of the brackets are arranged rods y which are surrounded by coiled springs 2, designed by virtue of their interposition between the lugs a and the lugs 03 to yieldingly press the frame N and the roller L inward and hold the latter against a cable and to its work. The roller M is carried by a similar frame N which is pivoted at w to the brackets J and K and is provided with apertured lugs 09 through which and the lugs o of the brackets extend rods on which are mounted coilec springs .2, designed because of their interposition between the lugs o and 00 to yieldingly press the frame N and the roller M inwardly. It will be readily understood in this connection that by virtue of the rollers L and M bearing against the cable at opposite points, with reference to the drum, and the roller D being located at a point intermediate the rollers L and M, the cable will be maintained under all conditions in superposed coils on the drum and will not be subjected to frictional wear during its passage to and from the drum.

P is a longitudinal central runner fixed to the under sides of the timbers a and the under side of the frame E and having beveled ends, and E, Fig. 1, is one of two comparatively short runners, fixed to the under,

sides of the timbers a and Z), and disposed at opposite sides of the runner P. The runners, as their name implies, are designed to facilitate movement of the apparatus over the ground.

S is ,a sweep plate disposed above the top casting B, as best shown in Fig. 9, and T is a sweep fixedt'o one end of the plate S and extending at a right angle therefrom. Between the opposite end of the plate S and the sweep T is arranged a brace rod U which serves to materially strengthen the connection between the two parts. The sweep plate S is provided, as shown in Fig. 3, with an opening a which is shaped in conformity to and is designed to snugly re ceive the angular portion Z) of the spindle Gr, whereby it will be seen that when the plate S is turned the spindle G will turn therewith. The said spindle G is provided at its upper end with a flange 0 bolted to the upper side of the sweep plate, and serving to prevent vertical movement of either the spindle or the sweep plate with respect to each other. The sweep plate S is proided at opposite sides of the flange 0, Fig. 2, with vertically disposed openings cl, through which extend vertically movable links which are connected at their lower ends to the vertically movable clutch member TV. The said vertically movable clutch member W is provided with an angular aperture 9 which snugly receives the angular portion Z3 of the spindle G, and hence it will be seen that the member W is adapted to be moved Vertically on and with respect to the spindle G, and yet will always derive.

circular motion from and turn with the said spindle which, in turn, derives rotary motion from the sweep plate S in the manner before described. On its lower edge the clutch member W is provided with teeth it corresponding to and adapted to engage the teeth of the drum, and consequently it will be seen that when the clutch member N is raised, as shown by dotted lines in Fig. 3, the drum F is left free to be turned in either direction independent of the clutch member, and it will also be seen that when the said clutch member is lowered to put its teeth/z in engagement with the teeth 70 of the drum, the drum will be caused to turn in the direction indicated by the arrow in. Fig. 2, with the clutch member W, the spindle G, the sweep plate S and the sweep T, it being understood of course that the sweep is then being moved in the direction indi cated by arrow by a team of horses hitched in the conventional or any other suitable manner thereto.

For the purpose of raising and lowering the clutch member 7 and adjustably fixing the same in different positions, I provide the mechanism best shown in Figs. 1, 3 and 5, which mechanism comprises a cross-bar m fixed on the upper end of the spindle G, vertically swinging levers p fulcrumed on the ends of the cross-bar m and having their lower arms pivotally connected to the links f", a keeper r fixed to and rising from the sweep T and having a transverse bolt 8, and a handle bar if pivotally connected to the upper arms of the levers p and having notches a at intervals of its length designed to be placed in engagement with the said transverse bolt 8 of the keeper. When the handle bar 6 is manipulated to rock the upper arms of the levers 79 toward the keeper 7" and thereby "arise the links f and the clutch member W, and the forward notch a of the handle bar is placed in engagement with the keeper bolt 8, it will be seen that the clutch member will be secured in its raised position, while when the handle bar t is manipulated to swing the upper arms of the levers p in the opposite direction and thereby lower the links f and the clutch member and the rear notch a of the handle bar is placed in engagement with the keeper bolt 8, it will be understood that the clutch member W will be secured in its lower working positioni. 6., in engagement with the teeth of the drum F.

It will be gathered from the foregoing that the handle bar 25 may be operated with facility by an attendant walking in rear of the sweep T and driving the animals hitched to the sweep, and consequently said attendant may, when occasion demands, put the drum F out of operation without stopping the team.
